Utah State Route 78
# Utah State Route 78

State Route 78 (SR-78) is a 9.418-mile-long (15.157 km) state highway in the U.S. state of Utah that serves as a connector from the town of Levan and SR-28 to Interstate 15 (I-15) and the Chicken Creek Reservoir. The route was formed in 1977 and has preserved its initial state since then.

## Route description

The road begins at a diamond interchange with I-15 at exit 207. From that point, the route heads northwest as a two-lane undivided highway, running almost parallel to I-15 in the west and Chicken Creek Reservoir in the east. Once the route passes the reservoir, it eventually turns north-northwesterly until reaching the intersection of a local road, where it turns east. The route enters Levan as 100 North and soon terminates at SR-28, the main street of Levan.

The east–west portion of SR-78 between Levan and Elevator Road is a part of the National Highway System.

## History

In 1975, as Interstate 15 was being constructed in the area, State Route 163 was designated along the old alignment of US-91 from I-15 at Mills Junction to SR-28 in Levan. Since this route shared a number with U.S. Route 163 in southern Utah, it was renumbered to SR-78 in the 1977 Utah state route renumbering. The only change that has occurred to the route since then was a change to the legal definition in 1987, making it more detailed.
